Page 15: Warnings, Cautions, And Notes
NOTE: Important information concerning the device. 2.1 Warnings • Do not use the BiPAP Vision in the presence of a flammable anesthetic mixture with air, oxygen, or nitrous oxide. • Oxygen supports combustion. Do not use oxygen while smoking or in the presence of an open flame.
Page 16: Cautions
Do not allow any liquid to enter the cabinet or the inlet filter during cleaning. • If the BiPAP Vision is exposed to temperatures near the specified limits for operating, storage, or transport temperatures, allow the device to acclimate to room temperature before use.
Page 17: Theory Of Operation
The PC board transmits process data to the main control (MC) board, which then provides overall control of the BiPAP Vision and sends instructions to the PC board regarding required ILFR-PRV valve stem positions and blower speed.
Page 18 Table 3-1: BiPAP Vision Subsystems Subsystem Function Power supply subsystem Provides the bulk supply DC voltage to the BiPAP Vision subsystems. (PSS) Main control (MC) board Performs all control, data acquisition, and calculations required for user-selected parameters. The MC board also performs the start-up test and reports all errors.
